ST. LOUIS (KPLR) – Changes are coming to the Edward Jones Dome after a pair of recent incidents on the sideline raised concerns over the concrete surface adjacent to the football playing field. The St. Louis Convention and Visitors Commission confirmed that a new NFL policy now requires “every horizontal surface within the stadium that a player may reasonably expect to contact during a game should be non-slip when contacted by a cleated shoe.”

The Edward Jones Dome came under fire after Cleveland Browns quarterback Josh McCown couldn’t stop on the surface after running out of bounds during a game last month. A week later, San Francisco 49ers running back Reggie Bush suffered a season-ending knee injury when he fell on the same concrete, away from the immediate sideline.

Word leaked out over the weekend that Bush was considering a lawsuit over the injury.

Marty Brooks, the Senior Vice President and General Manager at America’s Center & the Edward Jones Dome, said a 9,400 square-foot non-slip rubber surface from Mondo Sports flooring will be in place in time for Sunday’s game against the Chicago Bears. The costs tied to the new project will be covered by the Regional Sports Authority.

It was not immediately clear if the new league guidelines are impacting any other stadiums.

“The Edward Jones Dome prides itself on its long record of compliance with all NFL specifications related to field set-up and operations. This covering will be used for all football games for the remainder of the season,” Brooks told FOX2.
